How to Make a Events Platform App with Flutter

Ticket Tiers

class TicketTier {
  final String name, description;
  final double price;
  int available;
  int get sold => _initial - available;

  TicketTier({required this.name, required this.description,
    required this.price, required this.available})
    : _initial = available;

  final int _initial;
}

class TicketSelector extends StatefulWidget {
  final List tiers;
  const TicketSelector({super.key, required this.tiers});
  @override State createState() => _TicketSelectorState();
}

class _TicketSelectorState extends State {
  final Map _quantities = {};

  @override
  Widget build(BuildContext context) {
    return Column(
      children: widget.tiers.map((tier) => Card(
        child: Padding(
          padding: const EdgeInsets.all(12),
          child: Row(
            children: [
              Expanded(
                child: Column(
                  crossAxisAlignment: CrossAxisAlignment.start,
                  children: [
                    Text(tier.name, style: const TextStyle(fontWeight: FontWeight.bold)),
                    Text(tier.description, style: TextStyle(color: Colors.grey.shade600)),

                  IconButton(

                    }),
                  ),
                  Text('${_quantities[tier.name] ?? 0}', style: const TextStyle(fontSize: 18)),

UI & UX Suggestions

Use a vibrant event colours, purple VIP badge, green available indicator colour palette to match the app's purpose. Keep the navigation simple — a bottom nav bar or a single-scroll layout works best for this type of app. Make sure every interaction provides haptic or visual feedback so the app feels responsive and polished.
